Commentary
A compact linear phase speaker system with high efficiency and high input resistance.
A 18 cm cone type woofer is installed in the low range.
This unit uses a large magnet with a diameter of 75 mm to achieve rich low-frequency playback.
A horn type with magnetic fluid sealed in the magnetic gap is used for the high-frequency band. Heat generated by the voice coil is dissipated through the magnetic fluid to objects with large heat capacity such as yokes and pole pieces to enhance heat radiation effect and improve input resistance.
In addition, the magnetic fluid acts as a damper to cut unnecessary low frequencies and realizes low distortion.
A linear phase design is adopted in which the sound source centers of the tweeter and woofer are aligned in a straight line to improve the orientation.
The enclosure is a bass reflex type that uses TNRC, an acoustic material with excellent resonance resistance. Based on computer vibration mode analysis, two types of TNRC with mutually different vibration characteristics are combined in a well-balanced manner. Tomorrow.
Equipped with a hook for hanging on the wall.
Equipped with hook for joint connector that can be docked with separately sold Concise Compo SA-C07.
In addition to silver, there was also black type.
